Today, as part of Mobile World Congress 2018, we are excited to announce the first beta release of Flutter. Flutter is Google's new mobile UI framework that helps developers craft high-quality native interfaces for both iOS and Android. Get started today at flutter.io to build beautiful native apps in record time.

The thing about Flutter is that it's 100 percent Dart. Every widget in Flutter is assembled out of primitives similar to what something like Skia lets you do, but written in pure Dart. It's "Dart all the way down" so to speak. This makes sense if you think about the future of Fuschia: the idea is that you target Dart primarily; if/when Java or C++ Code is supported, it would likely be considered "legacy" in a similar manner to how Apple treats anything not written in Objective-C or Swift. From the perspective of this future platform, it's not really odd that they don't build off of something else.
